ALBERT B. HERRICK, OF RIDGEWOOD, NEW JERSEY, ASSIGNOR TO THE ELECTRICRAILWAY IMPROVEMENT COMPANY, OF CLEVELAND, OHIO, A CORPORATION OF OHIO.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed May 1904- Serial No. 206,496.

To all whom it may concern:

Be it known that I, ALBERT B. HERRICK, a citizen of the United States,and a .resident of Ridgewood, county of Bergen, and State of New Jersey,have in- 5 vented a new and useful Improvement in Apparatus forManufacturing Rail-Bonds, of which the following is a specification, theprinciple of the invention being herein explained and the best mode inwhich I have contemplated applying that principle so as to distinguishit from other inventions.

My invention relates to apparatus for manufacturing rail-bonds. andparticularly to a block about which a conductor is adapted to be woundto form such bonds.

Said invention consists of means hereinafter fully described andspecifically pointed out in the claims.

The annexed drawings and the following description set forth in detailcertain means embodying the invention, suchdisclosed means constitutingbut one of Various mechanical forms in which the principle of theinvention may be used.

In said annexed drawings :Figure 1 represents aperspective View of theimproved forming block used in my invention; Fig. 2 represents the samewith a conductor wound around it, and flux applied to some parts of suchconductor; Fig. 3 represents the same as Fig. 2 with transverse stripsor terminals clamped over the parts of said conductor to which the fluxhas been applied; Fig. 4 represents a perspective view of the conductorremoved from the block, and sawed into two similar parts; Fig. 5represents an end view of a transverse vertical section through theconductor, transverse strip and intermediate flux; Fig. 6 represents afront view of mechanism adapted to utilize said block for manufacturingthe bonds shown in Fig. 4; and Fig. 7 represents a side elevation ofsuch mechanism. I

The improved block used in my invention consists of a base A providedwith a raised surface or boss a, both of any desired shape or outline,and being shown as elliptical in the form of device illustrated. Saidblock is intersected by a transverse slot or fissure a which cutscompletely through the boss a and for some distance into the base A,and, in the device shown, passes through the center of the block, thusdividing the boss a into two similar parts. A small notch a is providedin the boss a, and the latter is cut away on both of its sides for asmall space as shown at a, said spaces intersecting the plane of theouter or main surface of the boss the purpose of which notch a andcut-away portions a will be hereinafter fully explained. Said improvedblock is utilized by winding a conductor around the boss a to form aplurality of rail-bonds, and, after said conductor is provided with fluxin certain parts and with transverse strips or terl l l l l I I the twosimilar bonds are complete.

minals, it is cut or separated into the individual bonds. Figs. 6 and 7represent apparatus for so utilizing the block, and the method ofoperation will now be set forth. I

The block is attached in any suitable manner to a shaft (1 operated froma shaft 6, and a suitable clutch f enables the block to be thrown intooperative relation with the shaft d. A suitable conductor C, Figs. 2 and3, is attached at one end to the boss a, being secured in the notch aand by the rotation of the block any desired quantity of the conductormay be wound in convolutions around the boss a. A quantity of flux a isthen spread over the wound conductor C transversely of the slot (1 andfor some distance on either side of the same, as shown. The block isthen placed under a suitable press or die G operated from a shaft gconnected with the shaft 6, as shown, and transverse strips a or whatserve as terminals in the finished bond, are securely fastened over theflux portions, one side of such strips a being secured in the cut-awayportions (1, and the other side about the outer strip 13 of theconductor C. The block is then fastened in a suitable casing H and theconductor 0 is cut into two similar bonds 0 and c by means of a saw Joperated from the shaft 0, such cut being made through the strips a andthe flux a, there being space provided for the operation of the saw J inthe slot a The end I) of the conductor C that has been retained in thenotch a is then pressed back against the inner periphery of the bond 0,and

It is obvious that the described improved block can be utilized tomanufacture more than two bonds at one operation by sawing the woundconductor into three or more parts; that said parts or the finishedbonds may not necessarily be similar or of the same size; and that ablock of an outline other than elliptical may be used Other modes ofapplying tne principle of my invention may be employed instead of theone explained, change being made as regards the means herein disclosedprovided the means stated by any one of the following claims or theequivalent of such stated means be employed. I

I therefore particularly point out and distinctly claim as my invention:I

1, In apparatus for manufacturing rail-bonds, a block provided with araised surface about which a conductor is adapted to be wound and withslots dividing said surface into a plurality of parts.

2. In apparatus for manufacturing rail-bonds, a block provided with araised surface of an outline similar to the combined outline of two ofsaid bonds about which a con ductor is adapted to be wound and atransverse slot dividing said surface into two similar parts.

In apparatus for manufacturing rail-bonds, a block provided with araised boss of an outline similar to that of the bond and around whichthe latter may be formed,

said boss having two oppositely disposed spaces cut into its sides.

4. In apparatus for manufacturing rail-bonds, a block provided with araised boss of an outline similar to that of the bond and around whichthe latter may he formed, said boss having two oppositely disposedspaces cut in its sides, said spaces intersecting the plane of the outeror main surface of the boss.

5. In apparatus for manufacturing rail-bonds, a block provided with araised surface about which a conductor is adapted to be wound and withslots dividing said surface into a plurality of parts, said raisedsurface having spaces cut into its sides at points adjacent to saidslots.

6. In apparatus for manufacturing raibhonds, a block provided with araised boss, of an outline similar to the combined outlines of two ofsaid bonds, about which a conductor is adapted to be wound. and atransverse slot dividing said boss into two similar parts, said bosshaving spaces cut into its sides at the points of their intersection bysaid slot.

7. In apparatus for manufacturing rail-bonds, a block provided with araised boss of substantially elliptical outline about which a conductoris adapted to be Wound, and a transverse slot dividing said boss intotwo similar parts.

8. In apparatus for manufacturing rail-bonds, a block provided with araised boss of substantially elliptical outline about which a conductoris adapted to be Wound, and a transverse slot dividing; said boss intotwo similar parts, said boss having spaces cut into its sides at thepoint of their intersection by said slot.

Signed by me, this 2" day of May 1904.
